Does anyone make an external GPU enclosure for 2Xdual slot cards?

I'm considering adding another A40 to my setup but my case doesn't have the space (or power) for it. It's a server chassis so there's no easy way to just pick the MB and put it in a new case, it's a bunch of custom connections off the PSU to the MB.

What would be perfect? A dual PCI external box that would allow me to put in 2 A40's using nvlink with 1 or 2 connections coming out of that box running back to the server into the existing x16 slot. It's easy to find a single slot version of what I want (link below), but I need it to have dual slots. Honestly I guess I could just buy two of these and figure out how to space them correctly, but the "jank" factor would be getting pretty high at that point. What would be perfect is a forced airflow chassis that has 2 (or more) PCI slots each with their own Oculink connection powered from a single external PSU. Then drop something like this into the server chassis and just run one cable over to each PCI slot on the external enclosure.
